This invention relates to a device for straightening bent automobile wheel spindles, and has for one of its objects to provide a novel device of this character which 5. shall be simple and inexpensive and shall be adaptedto permit spindles to be straightened easily and quickly.

lVith the foregoing and other objects in View, the'invention consists in the construction, combination and arrangement of parts illustrated in the accompanying drawings, wherein Figure l is a topplan view ofthe the straightening device with a spindle arranged therein.

Figure 2 is a. longitudinal sectional view taken on the plane indicated by the line 2-2 of Figure 1. V

Figure 3 is a transverse sectional view taken on the plane indicated by the line 3-3 of Figure 2. v i

Figure 4 is a transverse sectional :view taken on the plane indicated by the line 44 of Figure 2, and

Figure 5 is a transverse View taken on the planein'dicatedby the line 5- -5 of Figure 2.

The spindle straightener comprises a body 1 which is of tubular formation and made from steel and which is adapted to receive the spindle to be straightened. The bore 2 of the body'l is greater diametrically than the largest. corresponding dimension of the spindle 3.

A fulcrum or bending pin 4 extends across the lower side of the bore 2 between the transverse center of the bore and the inner end thereof, the inner end of the borebeing the one through which thespindle is inserted into the bore. The pin 4 has its end portions anchored in the sides of the body 1, and the intermediate portion of the pin is partly embedded in the lower side of the body. Guide pins 5 extend across the lateral sides of the bore 2 between the fulcrum or bending pin 4 and the inner end of the bore. Guide pins 6 extend across the lateral sides of the bore 2 between the transverse center of the bore and the outer end thereof; The guide pins 5 and 6 have their end portions anchored in the upper and lower sides of thebody "Theguide pins 5 are spaced apart for a distance greater. than the guide pins 6. The spindle 3 rests upon the fulcrum or bending pin 4, the inner and larger end portion thereof is positioned between the guide'pins 5, and the outer and smaller end portion thereof is positionedbetween theguidepins 6.

:A cap screw 7 is threaded through the u i per side of the body 1 centrally between t 'e guide pins 5, and acap screw 8 isthreaded through said side of theibody centrally be tween the guide pins6i A follower or pad block 9 is positioned between the' larger end portion of the spindle 3 and the lowerend of the screw 7 and a follower or'pad block 10 is positioned between'the smaller 'end 'portion of the spindle and the lower' end: of. the screw 8. vThe'followers or pad blocks 9 and 10 are provided in their lower sideswith arcuate recesses 11, for thereceptionofth'e end portions ofthe spindle 3, and are provided in their upper sides with concave fre cessesl2 for the reception, of the rounded lower ends 7 a and 8a of the screws? and 8.

In practice, the device is adapted for-the receptionofa spindle to be straightened by turning the screws 7 and 8 upwardly, ,and the spindle, is insertedv in the body 1 in a'manner to arrange'its inner and larger end portion between the guide pins 5 and its outer or smaller end portion between the guide pins-6.

downwardly: far enough to clamp the inner end of the spindlebetween'itself and them-1 ner end of the body. L The spindle is straight ened by turning the screw 8 downwardly,the resulting pressure on thespindle being ap plied thereto outwardly of the fulcrum or bending pin 4, with the result that thespindle is straightened. I The bent. spindle is shown by broken lines and the straightened spindle by solid lines in Figure 2.

From the foregoing description, taken in connection with the accompanying drawings, it should be apparent that the spindle may be easily and quickly inserted and clamped in the device, that it may be easily and quickly straightened after, being inserted in the device, and that it may be easily and quickly removed from the device after being straightened. Topermit the removal of the spindle it is only necessary to turn the screws 7 and 8 upwardly.

WVhile we have described the principleof the invention, together with the structure which we now consider the preferred embodisignatures.

ment thereof, it is to be understood that the structure shown. is merely illustrative and that such changes may be made, when. desired,.as fallwithin the scope of theinvention as claimed; i Whatis claimed is 1 LA device for straightening a. spindle, comprisinga body provided with a bore for the reception of the spindle, a fulcrum ex tending across the bore-and upon which the spindle: rests, guides extending across the bore at right. angles to the fulcrum, clamping means: carried by the body and engaging the upper side :of the spindle at one side of the fulcrurn,and bending means carried by the body andengaging the upper side of the spindle at the opposite'side of the fulcrum.

2. A device-for straightening a spindle, comprising a bodyprovi ded with a bore, a fulcrum or bending pin extending across the bore between the transverse center of the body and one endthereof, a screw threaded through the upper side of the body between said pin and end thereof, a screw threaded through the upper side of the body between said centerand the other end thereof, guide pins extending across the bore' at opposite sides of and parallel to said first screw, and guide pins extending across-the bore at opposite sides and parall el to said second screw.

3. A device for straightening a spindle,

comprising-a body provided with a bore, a fulcrum or bendin g pin-extendlng across the here between the transverse center of the body and one end thereof, a screw threaded through: thewupper side of the bodybetween said pin andren'd thereof, a screw threaded through the-upper side of the-bodybetween.
